how to separate text with multiple underscores and varying length of values

问题

a1=ac_tree_birch_NewYork_ext

a2=bc_animal_dog_Washington_des

How do I separate the text in the cells by the "_", since there is varying length of the cell values. I would like to use a formula, and not text to columns.

Thanks

Use the SUBSTITUTE function to change all underscores (e.g. CHAR(95)) to a large number of spaces (typically the entire length of the original string) and peel out the padded pieces with the MID function. Finish off with TRIM and an IFERROR 'wrapper'.

In B1 as,

=IFERROR(TRIM(MID(SUBSTITUTE($A1, CHAR(95), REPT(CHAR(32), LEN($A1))), (COLUMN(A:A)-1)*LEN($A1)+1, LEN($A1))), TEXT(,))

Fill both right and down.

This can likely be done via Flash Fill (Excel 2013+).

For the first row of data, enter your expected outcome in subsequent cells to the right. This is how you want the data broken up:

Then select your first cell of output data and click Flash Fill from the ribbon:

Do this for the remaining columns. This will fill the column based on the pattern recognized by Excel within your original data:

If a VBA solution is acceptable, you can write a wrapper around the VBA Split function:

Public Function Split2(s As String) As String()
    Split2 = Split(s, "_")
End Function

Then in your worksheet, select (say) cells B1:F1, enter

=Split2(A1)

as an array function (CTRL-SHIFT-ENTER), and out comes your data.

Hope that helps.
